The Siemens 3RV6011-1KA15 is a SIRIUS motor protection circuit breaker in the S00 frame, rated 12.5 A operational current with a CLASS 10 trip characteristic. Rated for 690 V at AC-3 duty and 50/60 Hz, this breaker handles motor starting currents up to that voltage class. Mounting position is unrestricted, and the screw-type terminals accept 2×(0.5…1.5 mm²) solid or 2×(0.75…2.5 mm²) stranded — common panel wire sizes.
S00 frame and panel fit
The 3RV6011-1KA15 measures 96 mm deep, 45 mm wide, and 97 mm tall. The any-position mounting means you can orient it vertically or horizontally inside the gland plate area without derating the trip curve.
Shock resistance is rated at 25 g for 11 ms per IEC 60068-2-27, and surge voltage withstand is 6 kV — figures that support installation in industrial panels subject to mechanical stress and switching transients.
The transverse auxiliary switch design and screw-type terminals for the auxiliary/control circuit match the standard SIRIUS accessory range. If you need to add a remote trip indication or a shunt trip, the same auxiliary blocks that fit the 3RV2 series also fit this S00 frame. Maximum switching frequency at AC-3 is 15 cycles per hour — enough for a pump or fan start once every four minutes, but not for high-cycling applications like a stamping press or rapid-index conveyor. For those, step up to a larger frame or a contactor with a higher rated operating frequency.
